  1. Left is 0.1mm offset, Right is 0.15mm offset Left is super smooth, right is smooth but you can see/ eel the individual lines of the bottom layer, so a bit too high
  2. EDIT If one uses the z offset tool, what would be the suggested distance to try? I wish I could adjust it at the beginning of a print (Marlin babystepping) I'm trying 0.1 and 0.15 to see how those go
  3. Hi, We have two Ultimaker S5's and noticed with active leveling, printing on glass, the prints are very difficult to release from the bed. Trying to improve from this, we purchased some magentic bed/spring steel/BuildTak sheets offered by PrintedSolid a while back. Due to the COVID thing, I haven't had a chance to try those out until this week (we are allowed back in the laboratory for short shifts for now). The prints release with that lovely spring steel wiggle but on one printer, you can see the "ghost" of the location where the print was. My experience with PEI surfaces have been you need to be a tad further away from the bed or the sheet will eventually fail (prints have to be peeled off or eventually rip the PEI sheet). On my home Marlin-based machines, I know I can Babystep my first layer and adjust it (ideally during the skirt layers of a first layer). How do others adjust for this? On the printer? In Cura? Thanks!
  4. Thanks for that. We're having a terrible time with this. We make sure two models are laid flat, we hit merge...and Cura throws them apart
  5. Thanks for those. My peer and I are still stumped so we may give up on this approach for now
  6. Been Googling with no results thus far. Thanks?
  7. Not to be picky, but why is "colorFabb", "eSUN" and 'igus GmbH" at the bottom and not sorted within the listing? Just curious.
  8. I'm trying to follow those steps but unable to sort out the "modifier mesh" and where to find the "Modify Infill Only" ? (I'm also having a hard time going between models once merged)
  9. Hi there. I have an Ultimaker S5 and I was hoping to print some multicolor labels to place on some toolboxes and cabinets. I have found some nice Customizable labels on Thingiverse but those only generate one file. I do not see a way to make it into two files, as the Cura documentation explains for multi-color prints. Is there a way to do this within Cura? To split up the model? For reference, I was looking at this... https://www.thingiverse.com/thing:2768920 It seems many people pause the print and change the filament [on their single filament printers] Thank you in advance.
  10. Perfect, thanks! It looks like a bad roll of PVA is the cause of my issues. But to be sure I have taken Erin's advice to install an AA core, load some PLA and do a print from extruder two. That's next!
  11. Interesting...we're seeing that the PVA is trying to prime off the side of the bed? How could that be fixed?
  12. Screwhead is inside, thanks for that reminder. It always makes that un-nerving SNAP when you open the feeder. I think I have narrowed it down a bit more. When feeding filament in, it doesn't seem to always hit the hole in the level to glide into the bowden. It definitely takes some finesse to get through there but it seems like more than usual. With the cover off, we can see how it should work. With the cover on (tension screw under the cover), we tension it to the middle position, per the service manual. This last time, we loaded PVA and heard a SNAP sound, and it broke the PVA in the tube. There was a few inch gap between the two segments, so we used the Move process to push them together. Side note, is there a way for the PVA extruder to do the prime blob as the primary one does at start of print (we checked that on in Cura) I know we can do a prime tower but that's overkill.
  13. I've been working with Erin over to support on this. To update, I've done some cold pulls on the BB hot end and the first one had a lot of PVA stuck to it. The second came out clean. I reloading the PVA and it was trickling out of the hot end. This morning I had a student start a print with support and nothing is coming out the PVA side. Still working through some ideas.
  14. Same here. But that’s the issue. Pushing the filament into the extruder isn’t smooth. There’s something about how it’s connecting to the bowden tube that seems problematic. It can take several shoves to finally get it in there. But that leads to the failure and grinding Only using new PVA that came with it
